3tera is among the pioneers in the cloud computing space, having launched its AppLogic system in February, 2006. Cloud computing is the set of technologies and business practices that enable companies of all sizes to build, deploy, monitor and scale applications using resources accessed over the internet. Web 2.0, SaaS, Enterprise and government users are adopting cloud computing because it eliminates capital investment in hardware and facilities as well as reduces operations labor.

On June 16, 2014, CA Technologies announced that AppLogic will be End of Life by June 30, 2015.[1][2]

3tera's flagship product, AppLogic, is used by numerous service providers as the foundation for their cloud computing offerings. AppLogic is a turnkey system that converts arrays of servers into virtualized resource pools that users can subscribe to in order to power their applications. Users can define not only virtual machines but also complex application infrastructure like firewalls, VPNs, load balancers and storage, all with nothing more than a browser. Service providers offer a variety of services based on AppLogic, including:

What generally distinguishes 3tera's model is that AppLogic is made available both as a service or as a software license. This allows customers to obtain service from a number of providers, move easily between providers, as well as operate in-house cloud computing services.
